[0110] FIG. 1 schematically shows an exterior, a second cabinet 21, and a front frame 220 of a laundry treating apparatus according to an embodiment of the present disclosure.

[0111] Referring to FIG. 1(a), in the laundry treating apparatus, a first treatment unit 10 is provided as a front load type, and a second treatment unit 20 is provided as a drawer type and a top load type. Thus, even if the first treatment unit 10 is provided at an upper position, a user can sufficiently access a door 12 provided at the first treatment unit 10, and even if the second treatment unit 20 is provided at a lower position, the user may access the clothing accommodating part provided inside the second treatment unit 20.

[0112] The first treatment unit 10 may include a first cabinet 11 forming an exterior thereof and provided with the door 12 at the front, and may include a plurality of legs 30 provided at a bottom to support the first cabinet 11.

[0113] The second treatment unit 20 may include a second cabinet 21 forming an exterior thereof and supporting the first treatment unit 10, and a drawer to be pulled out forward from the second cabinet 21 and capable of accommodating clothes, and a bracket 40 capable of supporting the legs of the first treatment unit 10 may be installed at a top of the second cabinet 21 (see FIG. 1(b)).

[0114] Referring to FIG. 1(b), the second cabinet 21 may include a body cabinet 210 forming a main body, a front frame 220 coupled to a front of the body cabinet 210 to form an opening through which the drawer 22 is pulled in and out, and a rear frame 230 coupled to a rear of the body cabinet 210 to cover the rest of the body cabinet 210.

[0115] The front frame 220 and the rear frame 230 may extend from the body cabinet 210 to be coupled to each other. However, unlike the drawings, the front frame 220 and the rear frame 230 may be coupled to the inside of the body cabinet 210. Accordingly, the rigidity of the front frame 220 may be further reinforced.

[0116] The front frame 220 and the rear frame 230 have C-shaped cross-sections, thereby structurally superior in rigidity and durability compared to the body cabinet 210. The bracket 40 may be disposed at a location corresponding to each corner of the top of the body cabinet 210. For example, the bracket 40 may be disposed on both sides of the front frame 220 and on both sides of the rear frame 230.

[0117] The bracket 40 may include a bracket body 41 seated on a top of the second cabinet 21, a protruding plate 42 protruding from an outer circumferential surface of the bracket body 41, and a leg receiving hole 43 penetrating through the bracket body 41 to receive the leg 30.

[0118] In addition, considering that a size of the first cabinet 11 seated on the top of the second cabinet 21 may change, the bracket 40 may further an auxiliary hole 44 extending in a diagonal direction from the leg receiving hole 43 to receive a leg of a first cabinet having a different size. In addition, a detection hole 45 in which a switch for detecting the first cabinet 11 being seated in the second cabinet 21 can be installed may also be installed in the bracket 40.

[0119] Referring to FIG. 1(c), the front frame 220 may include a load frame 221 coupled to both side surfaces of the body cabinet 210, an upper frame 222 provided to connect an upper end of the load frame 221, and a lower frame 223 facing the upper frame to connect a lower end of the load frame 221.

[0120] If the respective components of the front frame 220 are integrally formed, an assembly or welding process of each frame may be omitted.

[0121] Meanwhile, even if the second treatment unit 20 is provided as an auxiliary laundry treating apparatus, it is necessary to secure a washing capacity equal to or greater than a certain level, and an area formed by the opening of the front frame 220 needs to be enlarged in order to install a balancer or the like therein.

[0122] This is because the area formed by the opening determines a shape and a volume of the drawer 22, and the drawer 22 determines a washing capacity.

[0123] When the load frame 221 is extended to enlarge the opening, there is a problem in that not just the overall shape of the body cabinet 210 is changed, but also an installation height of the first treatment unit 11 is also changed.

[0124] Since the legs 121a may be installed at the bottom of the front frame 220, there is room for the lower frame 233 to be bent relatively further downward.

[0125] An extension bent portion 224 may be bent further downward than both ends of the lower frame 223 to enlarge the opening formed by the front frame 220 and also increase a height of the drawer 22 which is to be pulled in and out through the opening.

[0126] However, there is a limitation in that the extension bent portion 224 cannot be bent over a predetermined length or angle greater than as molded in the lower frame 223.

[0127] Since the extension bent portion 224 has no choice but to be formed within a plastic deformation range in which a material of the lower frame 223 may not be damaged, there is a limitation that a maximum level at which the opening of the front frame 220 can be enlarged is determined.

[0128] Thus, when the front frame 220 is molded as a single member, a volume of the clothing accommodating part accommodated in the drawer 22 may not be increased to or beyond an expected value, and a balancer for attenuating vibration of the clothing accommodating part and a volume or structure of a suspension supporting the clothing accommodating part may be limited.

[0129] Meanwhile, the extension bent portion 224 and the lower frame 223 of the front frame 220 may receive a load, a vibration, and noise. In this case, when the extension bent portion 224 and the lower frame 223 are spaced apart from the ground due to a leg, etc., the entire load transferred to the extension bent portion 224 and the lower frame 223 should be supported, which may lead to a durability issue.

[0130] In addition, the extension bent portion 224 and the lower frame 223 may vibration without attenuating the transmitted vibration, which may cause vibration and noise to propagate to the outside of the laundry treating apparatus.

[0131] Hereinafter, a laundry treating apparatus according to an embodiment of the present disclosure will be described in detail with reference to FIGS. 2 to 7.

[0132] FIG. 2 shows a laundry treating apparatus according to the present disclosure.

[0148] In addition, the second treatment unit 300 may be provided independently of the first treatment unit 200. That is, the second treatment unit 300 may be provided as an independent laundry treating apparatus.

[0149] Hereinafter, for convenience of description, an embodiment in which the second treatment unit 300 is disposed under the first treatment unit 200 will be described. However, all or a part of the structure to be described below may be equally applied no matter where the second treatment unit 300 is disposed.

[0150] The second treatment unit 300 may include a drawer 301a to be pulled out forward from the inside of the second cabinet 301. The second treatment unit 300 may include a second clothing accommodating part 302 and 303 for accommodating clothes in the drawer 301a.

[0151] A seating leg 210 may be provided under the first cabinet 201 of the first treatment unit 200. The seating leg 210 may be provided in plural. The seating leg 210 may be disposed on the second treatment unit 300.

[0152] Meanwhile, in order to prevent the drawer 301a from being overturned when the drawer 301a is pulled out, the second treatment unit 300 may operate only when the first treatment unit 200 is seated thereon.

[0153] When the first treatment unit 200 and the second treatment unit 300 are provided as a washing machine, the first treatment unit 200 may include a first accommodating part 202 and 203 provided inside the cabinet 201 to accommodate clothes.

[0161] The second treatment unit 300 may include a configuration having the same function as that of the first treatment unit 200, but in a different size.

[0162] The second treatment unit 300 may include a second clothing accommodating part 302 and 303 provided inside the second cabinet 301 and provided under the first treatment unit 200. The second accommodating part 302 may include a second tub 302 for storing water, and a second drum 303 rotatably provided in the second tub 302 and accommodating clothes.

[0163] The second treatment unit 300 may include a second driving part 304 provided on one surface of the second tub 302 to rotate the second drum 303, a second water supply part 305 for supplying water to the second tub 302, and a second drain part 306 for draining water from the second tub 302.

[0164] The second driving part 304 may be coupled to a bottom surface of the second tub 302.

[0165] Meanwhile, the first treatment unit 200 may include a first suspension 207 supporting the first tub 202 in the cabinet 201. The first suspension 207 may be provided as a combination of a spring 207a and a damper 207b, and may be provided as a combination of a bracket and a connecting bar.

[0166] The second treatment unit 300 may include a second suspension 307 for supporting the second tub 302 in the second cabinet 301. The second suspension 307 may be provided as a combination of a spring 207a and a damper 207b, and may be provided as a combination of a bracket and a connecting bar.

[0167] The first suspension 207 and the second suspension 307 may have any shape as long as they can support the first tub 202 and the second tub 302.

[0168] When the second treatment unit 300 is provided of a drawer type, a drawer 301a to be withdrawn from the second cabinet 301 may be provided, and the second tub 302 and the second drum 303 may be provided inside the drawer 301a.

[0173] The first treatment unit 200 may further include a first heater 208 for heating water to the first tub 202 and a first hot air supply part 209 for supplying hot air to the first tub 202.

[0174] The first heater 208 is preferably provided under the first tub 202, and a sheath heater may be applied.

[0175] Of course, the first heater 208 may have any shape as long as it can heat water in the first tub 202. The first hot air supply part 209 may include a duct for supplying air to the first tub 201, a duct heater provided inside the duct, and a fan for supplying air from the duct to the first tub 202.

[0176] The second treatment unit 110 may also include a heater 308 and a hot air supply part 309, as does the first treatment unit 200.

[0177] Meanwhile, the first treatment unit 200 and the second treatment unit 300 may include a power supply for supplying power to the first treatment unit 200 and the second treatment unit 300. The power supply may be a switch provided in the first cabinet 201 or the second cabinet 302, and may be preferably provided at one side of the display part 400.

[0178] Meanwhile, at least one of the first treatment unit 200 and the second treatment unit 300 may be provided as a drying apparatus. In this case, a treatment unit provided as a drying apparatus out of the first treatment unit 200 and the second treatment unit 300 may have all of the above-described configurations of the water supply part, the drainage unit, the tub, and the heater omitted therein.

[0179] Meanwhile, even if the first treatment unit 200 is disposed on the second treatment unit 300, the first treatment unit 200 may be overturned in the second treatment unit 100 due to the center of gravity being concentrated to one point or due to vibration, etc.

[0180] In order to prevent the overturn, it is necessary for the first treatment to be stably seated on the second treatment unit 300 even when disposed thereon. In addition, the first treatment unit 200 needs to be seated at an intended position on the second treatment unit 300.

[0181] However, the first treatment unit 200 has a considerable volume, and when the first treatment unit 200 is provided as a main laundry treating apparatus, the volume thereof may be significantly larger than that of the second treatment unit 300.

[0182] Thus, it is necessary to induce the first treatment unit 200 to be disposed at a correct position in an upper portion of the second treatment unit 300, and to stably fix the first treatment unit 200 to the second treatment unit 300.

[0183] To this end, the laundry treating apparatus according to the present disclosure includes a bracket 500 provided between the second cabinet and the first cabinet to support the first cabinet. When the first cabinet 201 is seated on the second cabinet 301, the bracket 500 may guide the first cabinet 201 to be placed at a correct position on the second cabinet 301.

[0184] The support leg 210 may be provided in plural at or near a vertex of a lower surface of the first cabinet 201. The support leg 210 may maintain and stably support the center of gravity of the first cabinet 201.

[0185] The bracket 500 may be provided separately from the second cabinet 301. Alternatively, the bracket 500 may be formed integrally with the second cabinet 301.

[0186] FIG. 3 is an exploded perspective view of the second cabinet 301.

[0187] Referring to FIG. 3(a), the second cabinet 301 may include a main body 320 for accommodating the drawer 301a, a fixed frame 330 disposed at one side or rear of the main body, and a pull-out frame 310 disposed at the other side or front of the main body to form an opening through which the drawer 301a is pulled out from the cabinet 301.

[0188] The pull-out frame 310 may be coupled to the main body 320. The pull-out frame 310 may be coupled to an inner surface of the main body 320. The pull-out frame 310 may support the main body 320. The pull-out frame 310 may be accommodated at the front of the main body 320 and coupled to the main body 320.

[0189] The fixed frame 330 may be coupled to the main body 320. The fixing frame 330 may be coupled to the inner surface of the main body 320. The fixed frame 330 may support the main body 320. The fixed frame 320 may be accommodated at the rear of the main body 320 and coupled to the main body 320.

[0190] The pull-out frame 310 and the fixed frame 320 may be each provided in a closed curve or a case shape to thereby maintain a shape of the main body 320 and distribute a load applied to the main body 320 mostly to the pull-out frame 310 and the fixed frame 320.

[0191] In addition, the pull-out frame 310 and the fixed frame 330 may be each provided with at least one of a thickness or a rigidity stronger than that of the main body 320 to thereby support most of the load applied to the main body 320 and maintain the shape of the main body 320.

[0192] Unlike the above description, the pull-out frame 310 may be coupled to the front of the main body 320, and the fixed frame 330 may be coupled to the rear of the main body 320. That is, at least one of the pull-out frame 310 and the fixed frame 330 may be exposed to an outside of the main body 320.

[0193] Meanwhile, although the pull-out frame 310 has been described based on an opening formed therein, the opening may be omitted when the second treatment unit 300 is provided as a general top load type rather than a drawer type.

[0194] In the main body 320, a space for accommodating the drawer 301a or the second clothing accommodating part 302 and 303 may be formed therein.

[0195] The main body 320 may be disposed under the first treatment unit 200. The main body 320 may include an upper panel 322 and side panels 321 extending downward from both sides of the upper panel 322. The upper panel 322 may form an upper surface of the second cabinet 301. The side panels 321 may form side surfaces of the second cabinet 301.

[0196] The main body 320 may be in a case shape, but may be open at front, rear, and bottom for manufacturing convenience.

[0197] The upper panel 322 may include a support groove 323 into which a separate buffer member for maintaining a distance between the second tub 302 and the drawer 301a during transportation is inserted. The buffer member inserted into the support groove 323 may extend upward from the upper panel 332 to support the first tub 202 positioned inside the first cabinet 201.

[0198] A reinforcement step 324 for reinforcing rigidity of the upper panel 322 may be provided along an outer circumferential surface of the support groove 323. Accordingly, even if a lower surface of the upper panel 322 is not supported by a separate member, the upper panel 322 may be maintained in shape without being bent downward.

[0199] A recognition blocking part 325 for generating diffuse reflection may be provided on both surfaces of the upper panel 322. The recognition blocking part 325 is a space in which a separate buffer member is seated in a case where a plurality of second cabinets 201 is stacked during manufacture or transportation. In this case, as the buffer member is seated for a long time, the surface of the second cabinet 201 may be contaminated or stained. In this case, the recognition blocking part 325 may generate diffuse reflection on the surfaces, thereby prevent the contamination or stain from being seen from the outside. In addition, the recognition blocking part 325 may be installed on the upper panel 322, thereby reinforcing the rigidity of the upper panel 322.

[0200] Meanwhile, a rail coupling portion 3211, to which a rail 360 with the drawer 301a to be pulled in and out there along, can be coupled or fixed may be installed in the pull-out frame 310 and the fixed frame 330.

[0201] Accordingly, the pull-out frame 310 and the fixed frame 330 having greater rigidity or durability than that of the main body 320 are capable of fully support the load of the clothing accommodating part.

[0202] The rail 360 may include a fixed rail 361 fixed to the rail coupling portion 322, and a pull-out rail 362 coupled to both side surfaces of the drawer 301a so as to be pulled out from the fixed rail 361 toward an opening formed by the pull-out frame 310.

[0203] A lower end of the side panel 321 may be bent inwardly to reinforce the rigidity of the side panel 321.

[0204] Meanwhile, the second treatment unit 300 may include a support leg 370. The support leg 370 may support a load of the second cabinet 301. The support legs 370 may be coupled to both ends of the side panel 321. Alternatively, the support leg 370 may be coupled to both ends of the fixing rail 361.

[0205] The support leg 370 may include a support damper 380 for buffering a transmitted impact. Accordingly, it is possible to absorb the impact that can be transmitted to the ground, thereby preventing propagation of noise. Since the first cabinet 201 is provided of a front-load type and the first driving part 204 is located at a rear surface, the support damper 380 may be installed only in a second support leg 370 located at the rear surface of the main body 320. Accordingly, It is possible to intensively buffer an impact in an area where a vibration occurs.

[0206] The fixing frame 330 may be disposed at a rear surface of the main body 320. The fixed frame 330 may be provided in the form of a frame having a C-shaped cross-section. Accordingly, it is possible to secure greater rigidity than that of the main body 320, and to support a load of the first cabinet 201 with the upper surface of the fixed frame 330 or both sides of the upper surface of the fixed frame.

[0207] In addition, the fixing frame 330 may be provided in a case shape with only one surface open. That is, the fixed frame 330 may be provided such that only a portion facing the main body 320 or the pull-out frame 310 is opened and one surface away from the main body 320 is shielded.

[0208] Accordingly, the fixing frame 330 may form the rear surface of the second cabinet 301, and may prevent the inside of the second cabinet 301 from being exposed to the rear surface.

[0209] The second cabinet 301 may include a lower panel 340 disposed under the main body 320. The lower panel 340 may cover at least a portion of a bottom of the cabinet. Due to the lower panel 340, the second driving part 304 or the drawer 301a may be prevented from being exposed at the bottom, and the rigidity or shape of the side panel 321 of the main body 320 may be maintained.

[0210] Meanwhile, the lower panel 340 may include: a panel body 341 coupled to a bottom of at least one of the main body 320, the pull-out frame 310, and the fixed frame 330; and an open hole 342 for exposing the second driving part 304 or discharging heat generated from the second driving part 304.

[0211] Accordingly, it is possible to prevent overheating of the second driving part 304, and to simply repair or installation of the second driving part 304.

[0212] The pull-out frame 310 may include a support frame 311 disposed at both front sides of the main body 320, a main frame 312 provided to connect upper ends of the support frames 311 provided on both sides thereof, and an expansion frame 314 coupled to lower ends of the support frames 311 to be aligned with the main frame 312.

[0213] The expansion frame 314, the support frame 311, and the main frame 312 may form an opening through which the drawer 301a is pulled out. The drawer 301a is provided to be pulled out from the pull-out frame 310 through the opening formed by the support frame 311, the main frame 312, and the expansion frame 314.

[0214] In this case, since the bottom of the main body 320 is open and the fixed frame 330 is shielded, a height of the drawer 301a may be determined by a height of the opening of the pull-out frame 310.

[0215] In addition, since the bottom of the second cabinet 302 is spaced apart by a predetermined distance due to the support leg 370, there is an enough space where the pull-out frame 310 is able to further extend downwardly. Thus, the expansion frame 314 may be bent further downward than the lower end of the support frame 311, so that the opening can further expand downwardly.

[0216] As a result, a volume of the drawer 301a may be expanded, and when the bottom of the drawer 301a is opened so that the second driving part 304 protrudes or the bottom of the drawer 301a protrudes further downwardly at a position corresponding to the second driving part 304, interference between the second driving part 304 (or the bottom of the drawer 301a) and the pull-out frame 310 may also be avoided.

[0217] Accordingly, as the internal volume of the drawer 301a is expanded, a larger washing capacity and the larger structure of a balancer and suspension part attached to an upper portion of the drum may be installed.

[0218] However, when the support frame 311 and the expansion frame 314 are integrally provided, bending the bottom of the drum 301a downwardly by deforming the expansion frame 314 cannot overcome the plastic deformation of the material and thus a rate of expansion may be limited.

[0219] Therefore, the increased washing capacity may not be sufficient, and there may be insufficient space for a balancer and a suspension structure to be installed.

[0220] In the laundry treating apparatus of the present disclosure, the expansion frame 314 may be provided separately from the support frame 311 and the expansion frame 314 may be bent downward.

[0221] Accordingly, the expansion frame 314 may be of a material having a greater degree of plastic deformation than that of the support frame 311. In addition, compared to a case where the expansion frame 314 is formed integrally with the support frame 311, the expansion frame 314 may be bent further wider and downward. Thus, the opening of the pull-out frame 310 may be further expanded, and accordingly, a height of the drawer 301a to be pulled out may be further expanded.

[0222] Therefore, the height of the second tub 302 may be higher, and accordingly, a larger balancer to be coupled to the top of the second drum 303 may be installed or a larger installation space of the second suspension 307 may be secured, so that a complex structure can be sufficiently installed.

[0223] The expansion frame 314 may be coupled to a lower end of the support frame 311. A seating portion 313 bent at the lower end of the support frame 311 and disposed below the lower end of the support frame 311 may be provided at a bottom of the support frame 311.

[0224] The expansion frame 314 may be coupled to a top of the seating portion 313. Due to the seating portion 313, the expansion frame 314 may be able to be completely coupled to the support frame 311 even if the material of the expansion frame 314 is soft or a downward bending amount of the expansion frame 314 is larger.

[0225] The seating portion 314 may extend from the lower end of the support frame 311 in parallel with the main frame 312. Thus, a length of the expansion frame 314 may be reduced within a length range in which the seating portion 313 is extended. In addition, it is possible to secure a greater bending amount for the expansion frame 314 to be deformed downward.

[0226] A space A (see FIG. 4) may be formed between the expansion frame 314 and the seating portion 313. Hereinafter, the space A may be referred to as a separation space A. At least a portion of the expansion frame 314 may be spaced apart from and coupled to the seating portion 313 to form a separation space A. The expansion frame 314 may be coupled to the support frame 311 at the bottom of the pull-out frame 310, so that the separation space A is secured.

[0227] Meanwhile, at the front of the pull-out frame 310 or the main body 320, a sensor s for detecting whether the drawer 301a is pulled out or whether a second door for opening and closing a loading port of the second tub 302 is opened or closed may be installed.

[0228] In addition, a frame support part 600 for guiding the pull-out frame 310 and the fixed frame 330 to be coupled to the main body 320 may be further installed.

[0229] The frame support part 600 may be provided at each corner of the main body 320 to provide a structure to be coupled to the pull-out frame 310 and the fixed frame 330. In addition, the frame support part 600 may provide a structure in which the bracket 500 supporting the seating leg 210 of the first cabinet 201 is coupled.

[0230] Referring to FIG. 3(b), in the pull-out frame 310, the seating portion 313 on which the expansion frame 314 is seated may be manufactured integrally with the support frame 311.

[0231] The seating portion 313 may extend from a lower portion of the support frame 311 provided on both sides, so that both ends of the expansion frame 314 can be seated therein. The seating portion 313 may extend inwardly from the lower portion of each of the both support frames 311 to support a bottom surface of the expansion frame 314.

[0232] The seating portion 313 may be provided not only to support the load of the expansion frame 314, but also serves to fix the expansion frame 314 to prevent the installation position of the expansion frame 314 from being changed.

[0233] The seating portion 313 may extend from the bottom of the support frame 311 in parallel with the ground. Alternatively, a free end of the seating portion 313 may extend to be positioned further lower than a lower end of the support frame 311. Accordingly, an area of the opening formed by the lead frame 310 may be further enlarged.

[0234] The seating portion 313 may include an extension panel 3131 extending from the bottom of the support frame 311, and bent ribs 3132 bent upward from both sides of the extension panel 3131 to form a space where the expansion frame is installed or the separation space A.

[0235] The expansion frame 314 may be fixed to the bent ribs 3132. The expansion frame 314 may be fixed to the inside of the bent ribs 3132.

[0236] The expansion frame 314 may include a seating body 3141 disposed between the bent ribs 3132 provided on both sides. The seating body 3141 may be at least partially spaced apart from the seating portion 313 to form the separation space A.

[0237] The seating body 3141 may include a support protrusion 314b extending from at least one of both side surfaces thereof to a bent rib 3132 and then coupled to or seated on the bent rib 3132.

[0238] The support protrusion 314b may arrange the seating body 314 on the bent rib 3132 so that the seating body 314 and the extension panel 3131 are spaced apart from each other. Thus, even if the seating body 314 is seated on the bent rib 3132, the separation space A may be formed between the extension panel 3131 and the seating body 314.

[0239] Even if the seating body 3141 is spaced apart from the extension panel 3131, the support protrusion 314b may be coupled to or seated on the bent rib 3132 to fix the installation position of the seating body 3141. The bent rib 3132 may include a seating groove 313a in which the support protrusion 314b can be supported. Thus, at least a portion of an outer surface of the support protrusion 314b may be brought into contact with an inner circumferential surface of the seating groove 313a or accommodated in the seating groove 313a, so that the seating body 3141 can be disposed and installed at a correct position.

[0240] The expansion frame 314 may include an insertion protrusion 314a extending from the seating body 3141 to fix the seating body 3141 to the seating portion 313 or the support frame 310.

[0241] The insertion protrusion 314a may pass through the support frame 310 or the seating portion 313 to fix the seating body 3141.

[0242] For example, the support frame 310 may include an insertion hole 311a into which the insertion protrusion is inserted and coupled.

[0243] The insertion hole 311a may be spaced apart from the extension panel 3131 by a predetermined distance. Thus, as the insertion protrusion 314a of the seating body 3141 is inserted into the insertion hole 311a, the seating body 3141 may be installed at the bent rib 3132 while being spaced apart from the extension panel 3131.

[0244] The support frame 311 may further include a support panel 3111 disposed at front of both sides of the main body 320, and a reinforcement panel 3112 bent and extending at both ends of the support panel 3111.

[0245] The insertion hole 311a may be formed in the support panel 3111.

[0246] The support panel 3111 may form a part of a side surface of the second cabinet 301 or may be disposed inside the main body 320.

[0247] The reinforcement panel 3112 may be bent and extend from the support panel 3111 to reinforce the rigidity of the support frame 311, and may be supported by being in contact with a front bent portion of the main body 320.

[0248] The support protrusion 314b may extend from a free end of the expansion frame 314 and be then inserted into the insertion hole 311a provided in the support panel 3111.

[0249] The insertion protrusion 314a may protrude outward from a free end of the seating body 3141, and the support protrusion 314b may extend at a position corresponding to an inclined direction or a vertical direction with respect to the direction in which the insertion protrusion 314a of the seating body 3141 protrudes.

[0250] Thereby, the positions of the support protrusion 314b and the insertion protrusion 314a may be separated, preventing an operator from confusing the components in assembling.

[0251] The insertion hole 311a may be spaced apart from the seating portion 313 by a height of the separation space A. Accordingly, when the insertion protrusion 314a is inserted into the insertion hole 311a, the separation space A may be formed between the seating body 3141 and the seating portion 313.

[0252] Meanwhile, the expansion frame 314 may be provided with a reinforcement bead 314c capable of reinforcing the rigidity of the expansion frame 314 in a longitudinal direction. The reinforcement bead 314c may be formed after the expansion frame 314 is inclined downwardly.

[0253] Furthermore, the expansion frame 314 may further include an avoiding groove 314d, so that interference with the second driving part 304 or a bottom surface of the drawer 301a accommodating the second driving part 304 can be avoided.

[0254] The avoiding groove 314d may extend along a thickness direction of the expansion frame 314 and may be provided in a downwardly recessed shape.

[0255] The avoiding groove 314d may be provided in an expansion body 3143 to avoid the second driving part 304 or a lowermost end of the drawer 301a.

[0256] The expansion frame 314 may be provided symmetrically. Thus, the seating body 3141 may be provided on both sides of the expansion frame 314, and the insertion protrusion 314a and the support protrusion 314b may also be provided on both sides of the expansion frame 314.

[0257] The expansion frame 314 may be provided such that a center is lower than both ends.

[0258] The expansion frame 314 may be provided in a shape extending from one end to the other end, bent downward, and then bent upward again.

[0259] Thus, the expansion frame 314 may further expand the area of the opening of the pull-out frame 310 downward.

[0260] The seating portion 313 may further include an expansion panel 3133 bent downward from the seating body 3131. The expansion panel 3133 may contribute to positioning the free end of the seating portion 313 lower than the support frame 311. The expansion panel 3133 may extend obliquely downward from the free end of the seating body 3131.

[0261] In addition, the seating portion 313 may further include a seating panel 3134 extending from the expansion panel 3133 to support the expansion frame 314. The seating panel 3134 may stably support the expansion frame 314 by expanding a contact area with the expansion frame 314.

[0262] Meanwhile, the expansion frame 314 may include an inclined body 3142 extending obliquely downward from the seating body 3141, and an expansion body 3143 extending from the inclined body 3142 to face the main frame 312.

[0263] The inclined body 3142 and the seating body 3141 may be provided symmetrically with respect to the expansion body 3143.

[0264] The bent ribs 3132 may extend from both side surfaces of the extension panel 3131 to both side surfaces of the expansion panel 3133. The bent ribs 3132 may be provided to fix the inclined body 3142.

[0265] In addition, the bent ribs 3132 may extend to both side surfaces of the seating panel 3134.

[0266] A height of a bent rib 3132 provided in the seating panel 3134 may be greater than a height of a bent rib 3132 provided in the expansion panel 3133 or the seating panel 3134.

[0267] Alternatively, the bent rib 3132 may be provided from the seating panel 3134 to the expansion panel 3133. Or the bent rib 3132 may be provided at the seating panel 3134.

[0268] In addition, the space A between the expansion frame 314 and the seating portion 313 may become narrower from the seating body 3141 to the inclined body 3142. That is, the inclined body 3142 may extend obliquely toward the expansion panel 3133, so that a thickness of the separation space A in the seating body 3141 becomes narrower.

[0269] Accordingly, pulling out the drawer 301a may not be disturbed.

[0270] In addition, the fixing frame 330 may have the same structure as that of the lead frame 310, except that the opening is not formed. That is, the fixed frame 330 may also include the support frame 311, the seating portion 313, and the expansion frame 314 to form the space A therein.

[0271] Furthermore, if the second cabinet 301 is disposed on the first treatment unit 200 or is disposed independently of the first treatment unit 200, the main body 320 may be provided to provide a space to accommodate the clothing accommodating part 302 and 303.

[0272] In this case, the lead frame 310 may be provided to form the separation space A, but may not form an opening like the fixed frame 330.

[0273] FIG. 4 shows the separation space A of the pull-out frame.

[0274] Referring to FIG. 4(a), the expansion frame 314 may be seated and coupled to the seating portion 313.

[0275] Both ends of the expansion frame 314 may be accommodated and coupled to the seating portion 313 and the bent rib 3132, and a central portion of the expansion frame 314 may be located lower than the lower portion of the support frame 311.

[0276] Referring to FIGS. 4(b) and 4(c), the support panel 3111 may receive a receiving groove 311b recessed from an outer circumferential surface of the insertion hole 311a toward the opening so that a free end of the insertion protrusion 314a can be accommodated.

[0277] The receiving groove 311b may be recessed inwardly from the support panel 3111, and may be recessed deeper at a thickness greater than a thickness of the insertion protrusion 314a.

[0278] Thus, the insertion protrusion 314a may be inserted into the insertion hole 311a and then bent to be seated or accommodated in the receiving groove 311b. Accordingly, the expansion frame 314 and the seating portion 313 may be coupled and fixed by themselves without an additional fastening member.

[0279] Meanwhile, the support protrusion 314b may protrude upward from the seating body 3141 and be then bent in a direction away from the seating body 3141. Accordingly, the seating body 3141 may be accommodated and supported in the bent rib 3132.

[0280] The inclined body 3142 may extend obliquely from the seating body 3141 so that a distance from the extension panel 3131 or the expansion panel 3133 becomes closer. In other words, the space A between the seating portion 313 and the expansion frame 314 may become smaller in a direction in which the expansion frame 314 is spaced apart from the seating portion 313.

[0281] As a result, the separation space A may be gradually narrowed, and the expansion frame 314 may be bent obliquely downward.

[0282] Accordingly, due to the separation space A, it is possible to secure the rigidity or durability of the pull-out frame 310, also not to intervene the drawer 301a from being pulled out.

[0283] In addition, at least one of the inclined body 3142 and the expansion body 3143 comes into contact with the seating panel 3134. Thus, the expansion frame 314 may be supported by being physically in surface contact with the seating portion 313 even if the space A separated from the seating portion 313 is present.

[0284] In addition, at least one of the inclined body 3142 and the expansion body 3143 may be coupled to the seating panel 3134 by welding or a fastening member and fixed thereto. Thus, even if the expansion frame 314 is provided separately from the seating portion 313, the same effect may be derived as if the expansion frame 314 is provided integrally.

[0285] Meanwhile, the reinforcement bead 314c may be provided in at least one of the seating body 3141, the inclined body 3142, and the expansion body 3143. That is, the reinforcement bead 314C may be provided by protruding from or being recessed in at least one of the seating body, the inclined body, and the expansion body.

[0286] For example, the reinforcement bead 314C may extend in a longitudinal direction of the inclined body 3132 and the expansion body 3143. In addition, a reinforcement beads 314C may be provided in plural such that a plurality of reinforcement beads is spaced apart from each other by a predetermined distance along a thickness direction of the inclined body 3142 and the expansion body 3143. Accordingly, even if the expansion frame 314 is of a material with high ductility but low rigidity, itis possible to secure sufficient durability.

[0287] FIG. 5 shows an effect of increasing a volume of a laundry treating apparatus according to the present disclosure.

[0288] FIG. 5(a) shows a front frame 220 of a conventional laundry treating apparatus, and FIG. 5(b) shows a pull-out frame 310 of a laundry treating apparatus according to the present disclosure.

[0289] Referring to FIG. 5A, since the front frame 220 of the conventional laundry treating apparatus is integrally provided, the front frame 220 has a limit in the length to extend even when bent downward.

[0290] In other words, even if a lowermost end of the lower frame 223 is further extended downward by bending a portion of the lower frame 223 to form the extension bent portion 224, a length of the extension bent portion 224 to be bent is inevitably limited due to limitation of the plastic deformation.

[0291] Thus, a maximum area of an opening that can be formed by the front frame 220 of the conventional laundry treating apparatus is limited, and a height of a clothing receiving part is also limited, and therefore, it is not possible to secure a washing capacity equal to or greater than a certain level.

[0292] In addition, since the lower frame 223 and the extension bent portion 224 do not form the separation space A therein, the cross section is provided in an “L” shape or “C” shape. Thus, only vibrations corresponding to an extending direction of the lower frame 223 are absorbed or dissipated among vibrations generated in the clothing accommodating part, except for vibrations in other directions.

[0293] Thus, the front frame 220 of the conventional laundry treating apparatus has a problem in that it does not guarantee durability in terms of noise and vibration and durability as well as a limited washing capacity.

[0294] Referring to FIG. 5(b), since the pull-out frame 310 of the laundry treating apparatus of the present disclosure is coupled in a state in which the expansion frame 314 and the seating portion 313 are separated from each other, an amount of plastic deformation of the expansion frame 314 and the seating portion 313 may be further increased.

[0295] Thus, by plastically deforming both the seating portion 313 and the expansion frame 314, the expansion frame 314 may be spaced apart further longer by h from the main frame 312.

[0296] As a result, the opening of the pull-out frame 310 may be further expanded to increase the height of the clothing accommodating part 302 and 303, and a washing capacity may be further secured.

[0297] Meanwhile, the expansion frame 314 and the seating portion 313 may form the separation space A therein, and the separation space A may have a cross section of a two-dimensional figure (for example, a polygon with more sides than a quadrangle).

[0298] Due to the separation space A, a load transferred to the seating portion 313 and the expansion frame 314 may be distributed to greatly increase the durability of the pull-out frame 310 itself.

[0299] Furthermore, a vibration transmitted in various directions (e.g., a width direction, a height direction, a front-rear direction, etc.) transmitted to the pull-out frame 310 may be supported by the entire separation space A.

[0300] In other words, the separation space A formed between the expansion frame 314 and the seating portion 313 serves to attenuate or dissipate noise or vibration transmitted to the pull-out frame 310 to a certain level.

[0301] The noise or vibration transmitted to the pull-out frame 310 may be dissipated to a certain level in the separation space A. Thus, even if the expansion frame 314 and the seating portion 313 are spaced apart from the ground, an amplitude of vibration may be greatly reduced when the vibration is transmitted.

[0302] In addition, a vibration transmitted to the extension frame 310 may be prevented from being transmitted to the expansion frame 314 as it is, so that the rigidity or durability of the expansion frame 314 can be secured and the expansion frame 314 may not generate noise and vibration.

[0303] In addition, an impact transmitted to the pull-out frame 310, for example, in a process in which the drawer 301a is pulled out, may be dissipated by the separation space A.

[0304] In addition, the pull-out frame 310 may distribute a transmitted load through the separation space A. Accordingly, by installing the separation space A in the expansion frame 314 and the seating portion 313, which receive the most load of the laundry treating apparatus, it is possible to sufficiently secure the overall durability of the pull-out frame 310.

[0305] In addition, the vibration transmitted to the separation space A may be dissipated in various directions along one surface of the expansion frame 314 and the seating portion 313.

[0306] As a result, seismic resistance of the pull-out frame 310 may be greatly increased.

[0307] Meanwhile, an earthquake-resistant effect may be applied even if the laundry treating apparatus of the present disclosure is not provided as a drawer type.

[0308] FIG. 6 shows another example of a second cabinet of a laundry treating apparatus according to the present disclosure.

[0309] In the second cabinet of FIG. 6, the lower panel 340 shown in FIG. 3 may be replaced with the lower frame 350.

[0310] Specifically, the laundry treating apparatus according to the present disclosure may include the lower frame 350, which is coupled to one lower corner of one side of at least one of the main body 320, the fixed frame 330, and the pull-out frame 310, and coupled to a lower end of the other side of at least one of the main body 320, the fixed frame 330, and the pull-out frame 310, the other side facing the one side.

[0311] That is, the lower frame 350 may extend along a longitudinal direction under the main body 320.

[0312] Both ends of the lower frame 350 may extend from the bottom of the main body 320 to the pull-out frame 310 and the fixed frame 330 and be coupled thereto.

[0313] Accordingly, the lower frame 350 may induce the pull-out frame 310 and the fixed frame 330 to be coupled to the main body 320.

[0314] The lower frame 350 may include a frame body 351 defining the main body, and a frame bead 352 provided concave or convex inside the frame body 351 to reinforce the rigidity of the frame body.

[0315] The frame body 351 may be bent downward along an inclination of the seating portion 313 or the expansion frame 314 in a direction inwardly from an outer surface of the second cabinet 301.

[0316] Accordingly, it is possible to prevent contact with the drawer 301a or the second driving part 304.

[0317] FIG. 7 is a view showing an effect according to a change in the installation structure of the second cabinet 301.

[0318] Referring to FIG. 7(a), the lower panel 340 may be coupled to the bottom of the second cabinet 301.

[0319] The panel body 341 of the lower panel 340 may include an avoiding groove for avoiding a space in which the support leg 370 can be installed at each corner. The lower panel 340 may be provided with a driving open hole 342 that exposes a space in which the driving part 304 is installed inside the driving part 304 or the drawer 301a.

[0320] Accordingly, heat irradiated from the driving part 304 may be discharged to the outside of the second cabinet 302.

[0321] In addition, a support member for separately supporting the driving part 304 may be inserted into the driving open hole 342. Thus, the support member may support the driving part 304 during transportation, thereby preventing damage to the internal structure of the second cabinet 302.

[0322] Meanwhile, referring to FIG. 7B, the lower frame 350 may be provided with a thickness that can prevent overlapping with the bottom of the driving part 304.

[0323] That is, the lower frame 350 may connect both sides of the second cabinet 302 to maintain the rigidity and shape of the main body 320, but induce the entire diameter of the driving part 304 to be exposed downward.

[0324] Thus, as all of the heat generated by the driving part 304 is irradiated to the outside, the driving part 304 may be cooled and it may be advantageous when repairing and replacing components installed inside the second cabinet 301, such as the drawer 301a.

[0325] Certain embodiments or other embodiments of the disclosure described above are not mutually exclusive or distinct from each other. Any or all elements of the embodiments of the disclosure described above may be combined with another or combined with each other in configuration or function.

[0326] For example, a configuration “A” described in one embodiment of the disclosure and the drawings and a configuration “B” described in another embodiment of the disclosure and the drawings may be combined with each other.
